soooo...you are saying I should go till the concentration roughly equals my water??? I thought it necessary to refresh each week, or even sooner(according to an article in Maximum Yield)...I wondered about the make up of the remaining nutes, is there an equal proportion to the starting formula??? what about just topping with a like concentration of the starting nutes, I thought the balance could be off...Not to be cheap or anything, just concervative...
WidowMaker Reviewed by WidowMaker on . Nutrients and yield :cool: Howdy Fellow Farmers!!!I use General Hydroponics Flora Series, according to the GH chart...I noticed the ppm concentration decreases rapidly, to about 50% starting strength in 7 days...and then I change it... I also now see a group of additives listed on their chart, Diamond Necter/Chi/Flora Shield/prysol, etc.... My question is, "Are these additives cost effective", ie., are they worth the added expense??? Furthermore, are there other less expensive nutrients to use yielding the Rating: 5
